The present invention provides an osteotome for sinus lifting and dental ridge expansion which includes an osteotome shank, a trepanelevation tip member, and a head. The trepanelevation tip member provides a cavity at a tip end and a prominence protruded from the bottom of the cavity. In this manner, during dental ridge expansion, the sharp edge of the trepanelevation tip member will secure the position and provide initial splitting of bones of sinus floor. Subsequently, the prominence will provide appropriate pressure for bone lifting. By applying the splitting force and compaction force alternatively in the same tip, the edge and prominence of the osteotome can lift the sinus in a much safer and more effective manner.
